panying'drawings, forming a part of the same.

Our invention relates to record controlled type casting and composingmachines, and more particularly relates to improvements in the meanswhereby the usual operations thereof are modified so as not to castcharacters ity is desired to omit from the composition. 7

Machines of this type have been illustrated in connection with theUnited States patent to G. A. Goodson dated August 16th, 1898, No.609,098, and also in Patent No. 715,233, dated December 9th, 1902,issued to WV. Ackerman, co-inventor of the present improvement, itbeing'the purpose of the presentinvention toattain this end in a moredirect and etfectualmanner.

I Vhile the preferredcform of our niacha-' nism illustrated herein isdesigned to operate in connection with a type casting machine, such asis described in our joint U. S. Patent 964,677, it is not desired tolimit the application of the same to that one form of machine, as withunimportant modifications it may be adapted to operate in conjunctionwith other forms of type casting machines. Nor is it essential that anypar ticular form of controller mechanism be employed to operate the,parts constituting our invention, and therefore the tape controllerdescribed in our joint United States Patent 964,678 which is adapted tooperate in connection with the type caster of our first mentioned jointpatent may be used, or the selector controller devices described in ourjoint Patent No. 964,679 may be employed with the sameresults, However,inasmuch as the present invention in its preferred form is applied tothe type casting machine described in our last mentioned patoutin thisconnection that in the use of the perforated tape controller of the typedef scribed in connection without first mentioned patent, a slightly.different order is followed in its preparation and presentation to thetype casting mechanism than insetting the separable'controllerdevicesfor selectors of theso-called one man machine described in oursaid joint Patent 964,679.

We will therefore briefly refer to the perti-,

nent features of the two methods, in so far as they relate to ourpresent apparatus.

Thus, in preparing the tape the operator wi]l by means of the proper keymake a special line cancel perforation in the strip in thespaceimmediately following matter to be omitted, in the place of the usualjustification perforation, which is immediately followed by the tripsignaling perforation. YVhen the ribbon is fed through the index headinits reverse order, as is usual in machines employing the tape recordpresentation, the trip perforation through the electrical contacts maythereby oause'the cam that constitutes the justifier partsto rotate,which as one of its functions will be made to actuate the mechanism ofour present invention which by operating special means presently to beexplained, is adapted to render inoperative the mold plunger actuatingmeans,rnot only during the setting of the justifier parts, which isnormally and automatically performed each timethe usual trip signalcontroller passes through the index head, but also for the extendedperiod covering the line cancel requirements, which is efliectedthrough'the action of the special line-cancelin erforation of the tapeabove'referred to. Such mechanism is necessary for the reason that themold plunger mechanism being actuated by the main driving shaft wouldcast a type at each revolu-f tion thereof, unless some means isespecially intervals.

provided to prevent its operating at certain Furthermore, inasmuch asthe driving shaft of the caster is carried through two rotations whilethe jiistifier cam is operating to set the justifier mechanism andperform the other functions relating thereto, it is obviouslyindispensable that the justifier cam should interpose preventive meansto the action of the plunger mechanism while said cam is performing theoperation above referred to. Therefore, as the trip perforation operatesto cause the justifier cam to rotate, which in the manner indicatedshuts on the pump mechanism from operating, it is only necessary tointerpose an independently operated locking device to the mechanism thusordinarily actuated by the justifier cam, which will retain the moldplunger in its in operative position indefinitely, or until the deadmatter of the controller has been run through the index head of themachine. This separate mechanism is made necessary for the reason thatthe justifier cam only holds the plunger mechanism out of commissionduring a certain portion of its revolution, which plunger mechanismwouldtherefore be free to operate to cast type immediately upon the justifiercam coming to its normal position of rest.

Therefore, having interposed such independent locking device which maybe termed the line-cancel latch mechanism, it is only necessary toconstruct such line canceling lock in amanner that will admit of itsautomatic release upon the succeeding revolution of the j'ustifier camwhich will necessarily be tripped at the commencement of the nextsucceeding line to be reproduced in type. That is to say, inasmuch aseach line of composition must preceded by a trip perforation, it isapparent that the line canceling lock will not need t6 be released untilthe new line is thus introduced into the composition, which isaccomplished automatically by the action of the cam upon the latchmechan1sm. I

The controller devices employed in connection with the mechanismillustrated in our said Patent 964,67 9, may be employed to cocperate'with the mechanism of our present invention, and are introduced into theindex head of the casting machine, in the same general manner in whichthe tape perforations are employed as above described. It is thereforenot necessary to describe in detail in this connection the methodwhereby the justifier selector is introduced into the procession ofselectors at theposition next following the trip selector at the head ofthose representing a given line, it bein apparent that the trip selectorin the practice of our present invention will be followed im mediatelyby a line cancel selector which will have its selective collar locatedby the mechanism described in said patent at a position features anelectromagnet which is energized to operate the actuating mechanism thatcontrols the line, canceling locking device, which in the preferred formof our present invention comprises as one of its essential by action ofa circuit closing device corresponding with the line cancel perforationor selector as the case may be.

Therefore, generically our in'iprovemen't includes in its complete formmeans for setting a controller device to operate a specially providedeiectromagnet which in turn will interpose a stop or latch mechanism inthe path of the slide which operates the mold plunger, therebypreventing the casting of the type until such latching is subsequentlyreleased. It will therefore be necessary in describing our invention indetail to include certain portions of the mechanism described in theabove patents, which incidentally are incorporated in the mechanism ofour invention, it being apparent, however, that several equivalentmechanisms can be used for the same purposes. 7

Where our invention is employed in connection with tape operatedmachines, or those of the one man type in which separable controllerselectors constitute the presentation record, the trip signal device inwhichever form employed will be followed immediately by a speciallyprepared signal device which will operate the line canceling mechanismof our invention, thus occupying the position normally assigned to thejustification perforation or selector as the case may be. 7

Heretofore, in connection with casting and composing machines,especially the electrically controlled class thereof, it has been thepractice to have an electrically operated mechanism to engage theconnecting rod which causes the pump plunger to operate to cast atype ateach rotation of the cam driving shaft, so as to throw that member outof engagement with its respective actuating 110 cam, thereby renderingthe pump plunger inoperative during the rotation of the justifier camwhile that member is scttin the justifier mechanism, at which time 0course no type will be cast. In our present invention 115 we havedevised mechanism whereby the j ustifier cam drum, by action ofspecially designed cam surfaces thereon, will automatically interpose alocking arrangement in the path of the pump rod so as to hold that 120member out of alinement with the pump operating cam on the main shaft ofthe casting machine, during the entire rotation of the justifier drum.

Hence, our invention broadly described 125 attains the object of theline cancellation by adding a mechanism whereby the locking device whichis operated by a cam on the justifier drum to scotch the pump rod, maybe held out of action indefinitely or until it 130 canceling look.

In the accompanying drawings, illustrative of a preferred embodiment ofour improvement, Figure 1 is a plan view of a part of a castingmechanism showing a portion:

of the driving shaft of the type casting mechanism with the justifiercam and mold plunger rod. Fig. 2 is a sectional side elevation of partsshown in Fig. 1, showing the line canceling locking device in positionto be thrown into engagement.

Referring to the drawings: 1 represents the frame of a type castingmachine of the class to which our invention applies, having a bed plate2, and a top plate 3 immediately above the bed'plate, and a main shaft 4which is supported by means not shown, upon the framework of themachine. Upon the shaft 1 are the several actuating cams of the castinmachine, only two of which are illustrate in the 'drawlngs in connectionwith our present invention, namely the'cam 8 which relates to the pumpoperating mechanism and the drum 15 upon which are the various camsemployed in connection with the setting of the justifier parts, whichwill be referred to as the justifier cam, having added thereon a specialcam 16 suitably arranged and timed to interpose a latch to lock the pumprod 5 from engagement with its cam 8. The justifier cam is looselymounted upon a sleeve upon the cam shaft 4, which sleeve is a part ofthe mechanism by means of which the cam 15 is intermittently clutched tothe cam shaft 4 through the action of a trip mechanism, fully describedin connection with our said joint Patent No. 964:,697, it beingsufficient to point out in this connection that whenever the trip isoperated by means of which an operable connection is effected betweenthe shaft 1 and the cam 15, whereupon the latter makes one revolutionwhile the shaft is passing through two complete rotations.

Slidably mounted upon the top plate 3 is the pump rod 5 which isoperably connected at one end with the pump plunger of the type castingmachine and is carried by spring action in the direction of the cam 8 onthe driving shaft, in order to operate said plunger to force the moltenmetal into the mold for casting type. Upon the opposite end of the slide5 is a cam roll 7 which by the sprinoaction above referred to, isoperably helcf in contact with the periphery of the cam 8, in which is adepression 9 into which the cam roll 7 is thereby thrust when thatportion of the cam is carried into the proper position to operate themold, the rearmost side of said cam depression being adapted by agradual incline to return the slide 5 in its normal position with theroll upon the periphery thereof, as the cam 8 continues its rotation. Inthis manner the pump is worked by the spring actuated pump rod 5 to casta type with each rotation of the driving shaft, unless held out ofengagement with its cam by other means which it is the purpose of ourinvention to provide and will now be described.

A hook lever 10 that has heretofore been employed to act as a safetylock on the pump rod 5 is pivotally mounted upon a bracket extendingupwardly from the top plate 3 and has its hooked end 11 adapted toengage corresponding toothed projection 6 upon the pump rod slide 5while the roll 7 rests upon the periphery of the cam 8. The hooked lever10 is therefore carried downwardly upon its-pivotal bearing in order tobe thrown into a position to hold the slide 5 in the manner indicated,from dropping into the depression 9 for the purpose of cast' mg type.

The hooked lever 10 is held normally in looking position by springyielding means 6, urging the hooked portion 11 into engagement with thetoothed member 6 so that it requires releasing means in order to permittype to be cast. To this end the opposite end of the hooked lever 10 hasan arm 12 which has a loosely pivoted finger 13 attached at the extremeend thereof and suitably held in a normally upright position by linkconnection with the frame of the machine so as to be contacted by theunder side of the matrix frame A which is hinged to the top portion ofthe machine, and when type are to be cast thereby is brought down intoposition contacting the member 13 and lifting the latch 11 at theopposite end of the hooked lever 10; so that at the succeedingrevolutions of the pump actuating cam 8, unless otherwise held out ofengagement therewith, the roll of the pump rod will drop into the notch9 of the pump cam and the plunger thereby operated to cast the type.Inasmuch, however, as it is necessary toief feet the line cancelingomission in the castring operation of the machine while the matrixframeA is in position to cast, it is found desirable to throw the latch11 into engagement with the tooth of the slide 5 while the matrix frameis in position to normally hold the latch 11 out of engagementtherewith. Consequently the finger 13 is made in two parts yieldablyconnected one to the other by means of a compressionspring 14 supportedupon a rod l4: so that as the matrix frame at A presses upon the top ofthe finger 13 it actuates the hooked lever 10 through yielding means towithdraw it from engagement with the tooth 6 so that the pump'rod may becarried by its spring to operate the pump when permitted so to do by thecam 8, asdescribed. 'Hence, while the hooked member is thus being heldout of engagement with the slide 5 to permit the pump plunger to act,other means must be employed to depress the hooked end of the lever 10into engagement with the tooth of the pump controlling slide 5 whenit-is desired to pre vent the casting of the type while the-machine isin operable condition otherwise. Such result is. accomplished in thepresent invention by means of cam block 20, 11 the hooked lever 10 uponthe top portion of which is the upwardly inclined cam surface 21, uponwhich bears a pin 23, projecting laterally from the swinging arm 22 thatis suspended immediately above theblock 20. As the arm 22 is rocked tothe right as shown in Fig. 2, the pin depresses thecam block, thesurface 21 of which isthere shown in its normalnnlocked positiominvthepath of the pin 23. on said arm.

The arm 22 is pinned to a rock shaft 24 suitably supported in a bracket2r upon the top plate 3 and is actuated by means of a lever arm 25 whichissecured to said shaft 2 1 by means of the set screw 25. At the freeend of the arm 25 is a stud 26 and loosely mounted thereon is a camrollf27 which is held, by action of the torsion spring 28 on the rockshaft 24, in yielding contact against the periphery of a cam 16securedto the justifier cam drum 15. Thecam 16 is so designedthat when the rollofthe, arm 25 is .restingupon the low portion thereof as bestshown inFig. 2, the pin of the swinging arm 22 is carried out of engagement withthe inclined portion of the cam surface 21 ofthe block on the latching.lever 10. having a raised portion thereon so designed that whenthe roll27 rests thereon, the pin 23 will have been forced along the surface 21withthe result that thelatohing lever .10 is thrown into engagement withthe tooth projection ,6 of the pump slide, thereby locking it so astoforestall the castingoperation. The high part of the cam 16 issufliciently prolonged so that it is .in contact with the cam roll tolock the pump throughout the major part of the rotation of the justifiercam covering all the setting operations thereof, during which period thepump is locked in the manner indicated. The cam however coming to itsnormalposition of rest as shown in Fig. 1, with the swinging arm 22brought into the low part of the cam surface of the block 20, permitsthe latch 11 to be carried out of locking engagement with the pumpplunger mechanism. Thus is attained the purpose of omitting the castingoperations during the circuit setting process when no type are to becast, it being necessary so to lock the pump mechanism for the reasonthat the main. driving shaft has rotated twice during. the revolution ofthe justifiercam, and but for theaction of the locking-mechanism at eachrevolution a type would have-been cast, whichwould of course notbeperniissible.

\Vhile the mechanism .as thus far explaincd would be adequateflinforestalling the casting operations during the .period occu pied by thesettingof the justifier-inechanism, it will be apparent that if theperiod of eliminating. type casting should be required to extend beyondthe mere setting operation other-mecl-ianism will be required.Therefore, when a number of characters or an entire line is desired notto'be cast, z'-.e.,.to be-canceled, instead of inserting ajustificationCQlltroller signal immediately after the trip signal in theusualway, a SPQClZLlfllllE cancel selector 0r=perforation is introducedat thatpo'int in the controller, which in our present form of mechanismwhen introduced into the index head, is designed to close an electriccircuit in which is included an electromagnet 35which is provided withmeans forholding theswinging arm 22indefinitely in alocking positionwith referenceto the cam block 200 1 the hook lever 11.

The means byv which theimagnet 35. accomplishes this locking purposecomprises a lever armature -36 pivotally supported upon a post 37 beingheldnormally outof contact with the magnet 35 by means of the spiralspring 38 secured to one side of the lever 36 at one end, secured at theopposite end to a pin suitably projecting from the post 3'7. llhearmature lever at its opposite end is adapted vto engage the bottom of alatch 40 whichis slidably mounted in a suitable bearing verticallydisposedlin the bedplate 3, upon the upper end of which is the toothedportion 11 adapted to engage acorrespondingly hooked end 46 of ahorizontal latch member 45 which is also slidably mounted in a bracketblock 47 and adapted to slide in a path immediately above the positionof the locking slide &0, and when the latter is held in its normalinoperative position shown in Fig. 1, to pass freely overthe headthereof. The vertically sliding latch member 40 is held in its normallydisengaging position by means of a coil spring 1-2 upon the stemthereof, there beingprovided for the purpose a collar 43 suitablysecured to the end thereof, the other end of the spring bearing, againstthe under side :of the plate 3 in which the slide 10 has its hearing.The horizontal sliding latch -member 45 .is connected by a short pitman48 which is pivotally mounted with the latch member 45 at one end beingat tached at its other end to the stud 26 upon the actuating arm 25 bymeans of which the hooked arm 11 is operated.

Gonsequently,.as the cam 16 rotates from the position shown in Fig. litforces the arms 22 and 25 outwardly, therebyperforming two distinctfunctions, namely, pressing the hooked lever 11 into locking engagementwith the pump rod, and at the same time carrying the horizontal slidingmember 45 into a position so that if the magnet be energized thearmature lever 36 will be carried against its spring 38 to force the vertical latch slide 40 upwardly into engagement with the slide 45, so thatas the cam 16 coming to its position of rest recedes from the roll theslide starts to return with it, but will now be held by the latch member40 in the position to which the cam 30 has carried it in which positionas has been seen, the cam of the hooked member, 11 is held to lock thepump rod. Thereupon the cam 30 remaining in the position in which itpresents the low portion thereof to the slide 45, that member is onlyheld by the latch 40, which is held in such position against the actionof its spring 42. The armature lever having immediately returned to itsnormal position of rest, the parts will therefore remain in this lockingposition with reference to the pump rod until the justifier cam throughthe action of a new trip selector signal is caused to make anotherrevolution at which time the cam 16 as its high part strikes the rollwill move the horizontal latch slide 45 just enough to release thevertical latch 40 which by action of its spring will be carried out ofengagementtherewith to allow the arm to fall back as the cam 16 rotates,thereby throw-' gized by a new line canceling impulse from a new linecancel selector signal, and the machine will resume its ordinaryoperation. Hence, the justifier cam 15 by action of the cam 16 therewithnot only forestalls the action of the pump rod during the circuitsetting operation, but also during the action of the working circuitsfor an indefinite number of rotations of the driving shaft or until suchtime as it is desired to start in with a new line of composition.
